chrysler imperial have built in radar detector?

92 Chrysler Imperial doesn't happen to have a built in radar detector or something that would detect radar and disable the cruise control?

Maybe just oddly a coincidence, but we were driving along about 70mph with the cruise on and then the car suddenly turned off the cruise, I look up and see a cop in the median with the radar gun out. We cruised on by without incident, but that was the first time I ever saw that happen. It wasn't my car, but I was driving. The owner rarely ever used cc so they never saw it happen.

Now this is a nice idea. Unfortunately, they would be villified by the safety ***** for doing anything like this.
It must be a convenient coincidence, to my knowledge no car maker has ever included an RD as standard. It would be nice if they put a slot somewhere up high, to give us an out of the way spot for an RD.

Well the only 2 options then are that it was just a wild wild coincidence or the cop had some kind of jammer. I would actually believe the coincidence to be more likely than the jammer. Even with how unlikely it is.
